APPARATUS FOR AND PROCESS OF MAKING COMMINUTED SOLDER.

SPECIFICATION forming part of Letters Patent No. 282,579, dated August 7, 1883.

Application filed June 8,1882. (No model.) I

To all whom it may concern: I

Be it known that I, EDWARD SMALL, a citizen of the United States of America, residing at Baltimore,- in the State of Maryland, have invented certain new anduseful Improvements in Apparatus for and Process of Making Coinminuted Solder, of which thefollowing is av specification, reference being had therein to the accompanying drawings.

The object of this invention is to provide an apparatus and process for making comminuted solder.

' In the drawings hereto annexed, Figure 1 is a vertical section of the apparatus. Fig. 2 illustrates the position occupied by the nozzles on a horizontal plane.

The letter A designates a solder melting receptacle; B, a furnace below, to heat the solder-receptacle. An air-chamber is formed above the solder-receptacle by a vertical cylindric case, 0, closed up at its upper end.

A discharge-pipe, F, leads from thebottom of the solder-receptacle, and serves to carry off the molten solder. At the end of this pipe is a suitable nozzle, g, for discharging a fine stream of molten solder. This nozzle is detaehable, so as to permit of ready removal, in

order to enable one of different size to be attached.

A pipe, H, leading from areservoir of compressed air, (not shown,) has a jet-aperture or fine nozzle, i, from which a blast of air issues.

A cock, k, is provided to regulate the blast or to entirely out it off.

A close chest or chamber, L, has a steampipe, a, entering one of its walls, whereby the said chamber is kept full of steam under slight pressure, a blow-off valve, 1), at-one side of the chest being arranged to open and allow the escape of steam whenever the given pressure (at no time great) is exceeded.

The nozzle 9 of the solder-discharge pipe and the nozzlez' of the compressed-air pipeboth enter through the walls of the close chest and discharge into the close chamber. These two nozzles, as well as the nozzle a of the steampipe n, are arranged with special reference to each other to accomplish a certain end, which will now be explained. In the first place, the air-pressure in the case cupon the molten sol-' der has the effect to drive the said solder through a nozzle, 9, having a much smaller aperture than it would flow through were no pressure employed, and this insures a finer stream of the molten metal, the said stream entering the close chest containing steam under pressure. of air crosswise of the stream of molten metal, and has the effect to break the said stream and scatter particles as of solder in a horizontal direction through the enveloping steam under slight pressure; at the same time the nozzle of the steam-pipe it throws a jet of steam crosswise of ,the path of the flying par ticles of solder, and serves to effectually scatter and chill said particles, which then fall and accumulate at the bottom of the chest.

The nozzle t delivers a blast Having described my invention, I claim and 4 breaking the said stream into small particles by means of an air-blast, and throwing a jet of steam crosswise of the path of the flying particles, as set forth.

2. The process herein described of making comminuted or fine-grained solder, consisting of running molten solder in a fine stream into a close chest containing steam under slight In testimony whereof I affix my signature in presence of two witnesses. I
